Problems solved by technology

There is a certain danger when the electric kettle is dry-boiled. In order to prevent the electric kettle from being dry-boiled, the existing electric kettle is generally equipped with a kick thermostat in the body of the kettle. When the heat of the metal sheet reaches a certain value (for example, 120°C), it deforms, thereby pushing the contacts away and disconnecting the power supply of the electric kettle.

Embodiment Construction

[0024] figure 1 A schematic flow chart of the electric kettle anti-dry boiling method provided by an embodiment of the present invention, as figure 1 As shown, the method provided in this embodiment may include the following steps:

[0025] S101. Detect the temperature of the heating tube of the electric kettle at a preset time interval, and calculate the temperature rise value according to the temperature of the heating tube.

[0026] Specifically, there is a heating device and a controller for controlling the operation of the heating device between the kettle body and the bottom cover in the electric kettle. The heating device is generally a heating tube, and the heating tube is close to the inner tank of the kettle body; For the pipeline connected with the inner tank, the heating tube is closely attached to the pipeline; or, the heating tube is connected with the inner tank. After the electric kettle is powered on, the heat pipe generates heat to heat the liquid in the in...

Abstract

The invention provides a method of preventing dry heating of an electric kettle and an electric kettle, wherein the method comprises: detecting temperature of a heating tube of the electric kettle in preset time intervals, and calculating temperature rise value according to the temperature of the heating tube; judging whether dry heating occurs to the electric kettle according to an average of the preset number of temperature rise values continuously calculated; if yes, controlling the electric kettle to stop heating. Dry heating prevention is achieved in electronic manner by the method and the electric kettle according to the technical scheme response speed is high, and errors in dry heating prevention judgment can be decreased.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for preventing dry heating of an electric kettle and the electric kettle. Background technique [0002] Electric kettle has become a liquid heating container commonly used in people's life due to the advantages of convenient use, safety and reliability, and easy portability. [0003] The electric kettle mainly includes: a pot body, a pot cover set on the top opening of the pot body, a bottom cover located under the pot body, and a heating device between the pot body and the bottom cover; shell. The heating tube in the heating device is close to the inner tank, and the electric kettle can be energized to make the heating tube start to heat the inner tank. There is a certain danger when the electric kettle is dry-boiled. In order to prevent the electric kettle from being dry-boiled, the existing electric kettle is generally equipped with a kick thermostat in...
